I have a 135 gal reef aquarium (mainly SPS). I wanted to keep a school of Blue Green Chromis. Someone suggested 15 chromises to disperse aggresion so that they don't pick each other off. Would this this be OK? Is this too high of a bioload (also have a pair of Ocellaris clowns)?

For tank specs, see my tank decription below.
 
They will still pick some of in my experience. It seems like you always wind up with about half as many as you start out with.
 
Add a midsized blue velvet damsel, a blue devil and a domino, and you will probably see them school. I had that combo in a tank, and the chromises did hang together most of the time.
 
i had 5 in my 135 and now there down to 3 : / i want to get 4 or 5 more though 15 would look really cool, i have a clown tang and the chromis are the only fish itl chase i think he just plays with im no nippin or anything, but its funny to watch, so the 3 shcool alright.
 
I have 13 blue/green Chromis in my 300gal (started with 15 a couple of months ago). I don't notice a lot of picking on each other, may be because of the numbers. They definitley spend a lot of their time together.
